BreezoMeter uses an index called “AQI (CY)”
We take the average of each pollutant type according to local government definitions.
An official conversion table is used to convert average pollutant concentrations to AQI for each pollutant.
The final AQI is determined by taking the worst AQI among all pollutants. The worst pollutant being the dominant pollutant.
AQI (CY) represents air quality levels according to the following health categories:
